Battery Doctor is a free app for Android (Google Play) and iPhone (App Store). Hailed as a “must have”, this app with more than 50 million downloads enables users to monitor battery status in real-time with details on battery usage broken down by feature and a task killer for managing power consumption.
Coolest feature: the screen where you can see how many minutes you’ll extend your battery life by toggling certain features off
Battery Doctor introduction video:
Some people swear by this app, and others insist its just a bunch of smoke and mirrors that contributes to battery consumption. I installed it on my 4S and gave it a try. I didn’t really notice any battery difference, but I do have to admit I mostly use my phone for web browsing and MP3s and I can get through a normal day with a good 40%-50% remaining (and this is on a three+ year old iPhone 4S).
- Predicted battery life savings for turning off certain features such as WiFi and turning down brightness
- Slightly more interesting charging screen
I didn’t like…
- Ads for games
- Overcharging warnings – I leave my phone charging overnight, every night, and it’s still running fine 3.5 years later
Overall, I didn’t really care one way or the other. Battery Doctor was quickly forgotten and later uninstalled when I remembered it later on.
